a beam l and standard 2. These parts2 may be oi-ordinary; construction.As illustrated, the heam and standard are of; integral formation. thestandardbeing formed with a slot 3 to receive the fastening meanswhereby the various shovels, earth treating devices or like parts areretained in place. Handle bars I4; areattached at their lower ends tothe, ;st andard 2 andbraces 5 conneetsuch handle, bars aviththe beam.These parts maybe ot any; construction and a arrange; ment aeeording tothe style of implement to which the invention is adapted, A recess 6is-form'ed in theafrontside'ofthe standard near its; lower; end.andextends transversely o f the standardfrom. one sideto the other and:constitutes a-seat to receive the shank oiitheisweep,runner, landside orother .analogou s-flpart, An-opening 7 is formedin a sideot the.standard 2 near the. recess or seat 6 ancl-is adapted to receive a pinor stud of the landside, runner or like-part that may. beplaeedinposition. The various-terms of types otshovels, earth treating devicesor like parts are formed with openings 8 which-are adapted to receivethelcatch or fastener 9. by means of which such shovels or similar.parts are securedto the standard. The catch or fastener 9 preferablyconsists of a hook and is pivoted to thelower end o f thelever 10 whichis arranged to operate intheslot 3 and is secured tothestandard by meansof a pin or pivct fastcning 11. The lever 10 curves to conform to theout line, oft-he standard 2 soas toententheslot 3th-ereo f and not be inthe way or notice- ,able when-the implement is in, operation or adjustedfor service. The catch 9 operates in theslot 3 and its hooked end isadapted to pass through the opening 8 otthe variousshovels; The-upperend of the lever 10 is formed with a tooth portion 12 which is adaptedto cooperatewith a latch 13 wherebyfthe leveris secured in the adjustedposition.

7 The latch 13 1S pivotedtothe beam l and ispreferably of U-form-so asto insure a substantial fasteningmeans forv the lever .and the latterpossesses sufficientinherent resiliency to permit-its toothed portiontobe readilyengaged withor disengaged-from the latch, and to beheldsecurely 'thereby when in -engagedrelation- The teeth shown at 12are -preierably of the well known ratchet or saw tooth shape in orderthat ac- I cidental disengagement of the toothed portion with respect tothe latch 13 will be prevented. It will be readily seen that, assumingthe parts to be in assembled relation, as seen in Fig. 1, by bearingdownward on the top portion of the lever 10 the latch l3 may be thrownforward, thereby releasing the lever and .permitting its upper endportion to be moved rearward, thereby. When the upper end of the latch13 is thrown forward the lever 10 is released and its upper end may bemoved rearward thereby throwing the catch 9 forward and releasing theshovel or like part held thereby. By having the catch 9 pivotallyconnected to the lever 10 such catch may be readily manipulated to passits hooked end through an opening 8 of the shovel or like earth treatingdevice or part both when placing such shovel in position or removing itfrom the standard. The sweep, runner, landside or other like part isformed with a shank which is fitted in the recess or seat 6 and isretained therein by the shovel or like part overlying the same andsecured to the standard by means of the catch 9 in the manner stated. Itwill be convenient to take up each member in turn, and in the followingparagraph reference will be made respectively to the sweep, runner, orlandside; and the formation of its recess engaging shank explained.

The numeral 14 designates generally the shovel, earth treating device oranalogous 7 part which is adapted to be removably fitted to the standard2 such part having the form best adapted for the particular work in handthereby admitting of the implement being used as a plow, a. cultivator,cotton sweep or the like.

The numeral 15 designates a landside, runner or like part, the samebeing placed against a side of the standard 2 and having a laterallyextending shank 16 which is adapted to fit within the seat 6, such shankhaving its outer end bent as indicated at 17 to extend along theopposite side of the standard and thereby prevent lateral displacementof the part 15. A stud 18 projects laterally from th part 15 and isadapted to enter the opening 7 formed in the side of the standard 2thereby relieving the shank 16 of excessive strain.

The numeral 19 indicates a double sweep, the members of which areconnected by means of a cross piece 20 which corresponds with the shankand is adapted to enter the recess or seat 6 and be retained therein bythe overlying shovel or like part 14.

It will be seen that the shank portion 16 or 20, as the case may be,when seated in the transverse recess 6 of the standard. constitutes anobstruction whereby the pivotal movement of the hook or catch member 9in a downward direction will be limited, thereby preventing thepossibility of said catch member being accidentally disengaged from theslot in thesuperposed blade or shovel. It will, therefore, be seen thatthe obstructing element occupying the recess 6 is an essential featureof the device.

It will be understood from the foregoing taken in connection with theaccompanying drawings that the invention is of such a nature as to admitof a shovel, landside or like part or parts being easily and quicklyplaced in position or removed, since no bolts or nuts are required to beremoved or loosened, the construction admitting of the catch or fastener9 being instantly released or made secure so that the required part maybe placed in position or removed with the greatest facility.

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains, and while we have described theprinciple of operation of the invention, together with the device whichwe now consider to be the best embodiment thereof, we desire to have itunderstood that the device shown is merely illustrative, and that suchchanges may be made when desired as are within the scope of theinvention as claimed.

Having thus described the invention, what is claimed as new is 1 Inanimplement of the character de- 1 provided with a transverse recess, alever 4 fulcrumed in the slot of the standard and having a pivotedhook-shaped catch projecting beyond the face of the standard, animplement having a shank seated in the transverse recess in the path ofthe pivoted catch, and a shovel having a slot engaged by the pivotedcatch, said lever having a toothed portion, and said lever possessinginherent resiliency; and a U-shaped catch pivoted on the beam to engagethe toothed portion of the lever.

3. In an implement of the character described, the combination with aslotted standard having a transverse recess in its catch pivoted on saidlever, and means for 10 securing the lever in adjusted position.

In testimony whereof We aflix our signatures in presence of twowitnesses.
